Hurricane Harvey

Drainage Network Repairs

(UPDATE: The Harris County Flood Control District has compiled a preliminary list of $74 million in priority repairs for Harris County’s bayous, creeks and other drainage infrastructure in the aftermath of Hurricane Harvey, according to a recently completed county-wide assessment that is expected to eventually top $100 million. The Flood Control District has verified approximately 500 repair projects totaling more than 150 channel miles across Harris County’s 22 watersheds. Some priority repairs are already complete or in progress. Since late August, the Flood Control District has committed almost $6 million in local dollars for initial emergency repairs and authorized nearly $4.9 million in projects, which are eligible for federal reimbursements.)

The $74 million estimate to repair countywide Harvey drainage infrastructure damage is preliminary and does not yet include repairs to stormwater detention basins. The number of priority repair projects will likely grow, and the total cost of those repairs is expected to exceed $100 million. Final estimates will be available as Flood Control District staff set individual project limits and perform additional assessments. Those projects will be submitted to the Federal Emergency Management Agency and other federal agencies that assist in disaster recovery for reimbursement under the federal Hurricane Harvey disaster declaration. 

The Flood Control District considers a number of factors in prioritizing drainage infrastructure repair projects, including whether the damage poses an immediate and severe threat to residential or commercial areas, or to public infrastructure such as utilities or schools. Repairs such as sinkholes and slope failures, failed outfall pipes and concrete voids also are prioritized according to severity.
